Bounds on the fine structure constant variability from FeII absorption lines in QSO spectra
Paolo Molaro, Dieter Reimers, Irina I. Agafonova +1
The Single Ion Differential alpha Measurement (SIDAM) method for measuring fine stucture variations (daa)and its figures of merit are illustrated together with the results produced…
A new approach for testing variations of fundamental constants over cosmic epochs using FIR fine-structure lines
S. A. Levshakov, D. Reimers, M. G. Kozlov +2
Aims. To obtain limits on the variation of the fine-structure constant alpha and the electron-to-proton mass ratio mu over different cosmological epochs. Methods. A new approach ba…
A new measure of Delta alpha/alpha at redshift z = 1.84 from very high resolution spectra of Q1101-264
S. A. Levshakov, P. Molaro, S. Lopez +5
We probe the evolution of the fine-structure constant, alpha, with cosmic time. Accurate positions of the FeII lines 1608, 2382,and 2600 A are measured in the z = 1.84 absorption s…
